GRAIN-BINDER.

SPECIFICATION forl'ming part of Letters Patent No. 234,806, datedNovember 23, 1880.

Application filed January 23, 1880.

To all lwhom tt may concern Be it known that I, HENRY E. PRIDMORE, ofSpringfield, in the county of Clarke and State of Ohio, have invented anImprovement in Grain-Binders, of which the following is a specification.

My invention relates to grain-binding machines, but more particularly tothe mechanism by which the gavel is bound and the knot tied; and itconsists in the construction, ai rangement, and operation of certainmechanism, which is fully and clearly set forth in the specification,and referred to in the appended claims.

In the drawings, Figure l is a perspective view of my improvedknot-tying mechanism, looking up from beneath the machine. Fig. 2 is aplan of same, looking up from beneath. Fig. 25 is afront elevation ofsame. Figs. 4, 5, and l5 are detached views of the cord-holder, knife,and tyinghook. Fig. Gis aperspective View of the tying mechanism proper.Fig. 7 is a section of same. Fig. S is a plan of same. Figs. 9 to 14 areviews of the cord during the progress of tying the knot.

A is a binding-frame, which rotates upon a vertical axis within thebearing A. Upon its outer end, and free to slide thereon, is an obliquesliding plate, B, which is provided with a rack, C, slot D, and acam-projection, E.

Motion is imparted to the slide B by means of the lever F andconnecting-bars F and F2, the bar F being in its turn operated by thecam-plate G, to which it is connected by the pin f. This cam-plate G ispivoted to the frame A at G. It is provided with a camslot, g, and asmall pivoted cam, h2, which is pressed against a pin or projection by aspring, and which operates the knife to sever the cord.

Working in the cam-slot g is aroller or pin, h, which is attached to theend of a bar, H, guided by a link, h. This bar H operates the knife tosever the cord when it is drawn back by the roller or pin 7i strikingthe cam h2, as hereinafter set forth.

The cord-holder I is pivoted at I obliquely to the frame'A, and isprovided with a pin or roller, z', which works in the slot D, andthereby governs the motions and time of movements is thrown up orallowed to be depressed by the cam-piece E, and insures the movement ofthe holder, so that it shall be thrown to or .from the tying mechanismproper at the required instant. rIhe holder, when thrown out, restsagainst a pin, a, onl the frame A.

The jaw J, carrying the knife, slides in a box, J', secured to theholder I, and is connected to the bar H by the pin jf. The end of thejaw is provided with two teeth, j and j', which work between two teeth,k 7a', on the holder I, as shown in Fig. 5. l/Vhen the teethj and 7cpass each other the cord is severed.

Secured to one side of the holderIis a springfinger, L, the end of whichis between the teeth jf and k. The oord is held between the tooth kandlinger Ii, the springing action of the latter insuring a rm hold.

Upon the holder I is secured a tying-hook, M, which can be set forwardor back with referenee to said holder by means of a screw, m, which,when tightened, presses it forward, and when loosened allows theresilience of the bent rear arm to draw it back. 4

The knot-tyer proper, N,`is secured to the frame A by the foot a, whichpasses through the slot I) in the sliding plate B. The casing N', openon one side, is secured to or forms part of foot n. A pinion, O, is heldwithin said casing by a shoulder, the outer face of said pinion beingformed into an incline plane, 0, and terminating in a hook, I). Withinthe casing N and pinion O is another piece, Q, which is secured to theeasing and has an opening, q, all the way through it. At the outer end,and on one side of the opening, is a projection, S, and on the otherside is piece It, attached to a spring, r, which is secured to the pieceQ at the inner end, as shown in Fig. 7. The hook M, attached to andoperated by the holder I, is thrust through between the projection S andpiece It when the loop is being made, and when withdrawn it carries theends of the cord with it through the loop, tightening the knot by thespringing action of the spring r and piece R. The pinion O meshes withthe rack G, and as said rack is reciprocated the looper composed ofthepinion, with its inclined plane and hook, is rotated 5o of said holder.There is also a pin, i', which first in one direction and then in theother.

Secured to the casing N is a shield, n', which covers the rack andprevents the cord being caught therein.

The knetter and its appendages are set in an oblique position withreference to the grain table or platform for the purpose of properlypresenting the bindingcord to said knottei, that in its revolution itshall catch and loop the cord in such a manner that the cords shallremain distinct and the loop easily operated upon.

Secured to the frame A is a curved finger, T, which partly encirclcs thelooper, the end resting on the inclined plane until the hook P reachesit, when it is pressed out, thereby allowing the loop which had beenpreviously kept between the iinger and incline plane to pass to theother side of the finger prior to the final action in tying the knot.

The hook P is so constructed that the opening forming the hook isparallel to the axis of rotation of the looper, or to the axis aboutwhich said hook rotates. Thisis clearly shown in Figs. 6, 7, and 8.

The guide U, secured to plate A, insures the proper presentation of thecord to the knot-tyer. A platform, V, is secured to the frame A androtates with il'. Situated over the platform is the biiider-arin YV,which presents the cord to the knot-tying mechanism. It is secured tothe end of arocking shaft, W', which rocks in bearings X X. Thecam-plate G is oscillated by any suitable means.

The operation is as follows: The cord being placed in the holder andpassed around the gavel, as shown in Fig. 1, the binder-arm W descendsand presents the cord to the holder. The cord is then as shown in Fig.9. The cani plate G is then oscillated, which action draws the teethjjin and holds the cord firmly. It also throws out the plate B and rack C,which rotates the looper, the hook P catching the cords and carryingthem around to forin the loop. The roller t', following the cam-slot D,causes the holder I to be projected toward the looper, giving cordwherewith to make the knot. As soon as the looper has made onerevolution the cord is in the form of a loop, as shown in Fig. 10, thehook P being at the point y. As the looper continues its revolution theloop is ready to slip from under the finger T, as shown in Fig. 11, inwhich yindicates the position of the hook P. As it continues to rotatethe pin h passes the cam h2, pressing it up. The plate B moves the endof the cam-slot D to the roller i, projecting it and the entire holdertoward the looper. At the saine time the loop is freed from the finger Tas the twister rotates, and the cord assumes the position shown in Figs.6 and 12, in which last gure y shows the position of the hook P. Duringthe movement of the holder I toward the looper the hook M is projectedto its greatest extent through the piece Q, and presents the hook to thepart of the cord next to the holder, as shown in Fig. 6. The cam-plate Gis then oscillated in the opposite direction. When the pin 7L strikesthe cani h2 itis drawn back, which action draws the knife-tooth jfarther into the holder and severs the cord. The looper is now rotatingiii an opposite direction, which frees the loop from the hook P, and atthe same time the holder recedes, carrying with it the hook M, which, inturn, carries the ends of the cord through the loop, as shown in Fig.13. The cani-plate G still moving, the holder is thrown back and thejaws opened for the reception of fresh cord from around a new gavel, andat the saine time the hook M carries the ends of the cord down betweenthe projection S and the spring-head It, which tightens the knot, asshown in 14. The bindenarin is thenraised and the bundle discharged fromthe platform.
